With five reel, three rows and 10 fixed paylines, players can spin the reels to enjoy wilds, expanding symbols and a big free spins bonus round where players can win up to 5000x their total stake. If you want to learn more about this slot game, check out the rest of our Cosmic Voyager review below.

How to Play

Players can get started playing Cosmic Voyager in just a few simple steps. Use the bet button under the reels to toggle your bet per spin which can range from 10p per spin to £100 per spin. The paylines in this game are fixed, which means less for players to toggle before spinning. This game offers an autoplay feature where players can choose their bet and the number of spins that they want, up to a maximum of 5000, before letting the game play automatically. Hit the black arrow spin button once your bet is decided to send the reels tumbling.

The symbols on the reels of this game are:

  • Purple Planet
  • Blue Planet
  • Green Planet
  • Pink Planet
  • Orange Planet
  • Blue Triangle
  • Green Square
  • Orange Shape
  • Gold Star
  • Cosmic Voyager Logo
  • Gold Mask


The highest value symbol on the reels is the gold mask and landing five on the reels will award 250x your stake. During the bonus game, and with the addition of expanding symbols, players can potentially win up to 5000x their total stake.

Special Features

There are three special features in the Cosmic Voyager slot game including:

  • Wild symbols
  • Expanding symbols
  • Free spins

The game logo is the wild symbol, and also the scatter symbol, and this substitutes for other symbols on the reels to help form new winning combinations which can lead to more cash prizes.

Stacked symbols appear on the reels of this slot game and when three appear stacked on reel 1 this will trigger the expanding symbols. Whenever you get a winning combination, any symbols in that combo that match the stacked symbols will then become expanding symbols. These symbols cover entire reels and if you get the gold mask as the stacked and expanding symbol, there is the chance to get as much as 2,500x your stake per spin.

10 free spins are awarded each time you land three, four or five of the Cosmic Voyager game logo symbols. Plus, depending on the number of scatter symbols you land, you will be awarded an initial pay out of 2x, 20x or 200x. As you start this feature, one medium to high value symbol from the first reel will be chosen and this will be stacked three places high, triggering the expanding symbols and resulting in bigger wins up for grabs. Landing a further three or more of the scatter symbols on the reels will award another 10 free spins and this is unlimited.

Graphics and Sounds

Cosmic Voyager transports players into space with its intergalactic graphics. Players can expect top quality graphics from this game, with a mesmerising galaxy setting the scene behind the reels. Above the reels is the gold mask wearing character who is animated throughout the game and helps to control the reels. The low value symbols in the game are different coloured planets, while the high value symbols include gold stars, a gold mask and other colourful shapes. Otherworldly music plays in the background as you spin the reels which contributes well to the space theme of the game.


Overall, Cosmic Voyager is a fantastic addition to the Thunderkick slots library that players will not want to miss out on spinning. The graphics in this game are gorgeous and will mesmerise players as they spin. Furthermore, there is a good range of bonus features in this slot game and lots of big cash prizes are up for grabs with the free spins bonus round and expanding symbols. Players are sure to notice some similarities here with NetEnt’s Starburst, so if that was a game you liked spinning, Cosmic Voyager will be a great slot to spin.
